2023-10-26PCI: hotplug: Add Ampere Altra Attention Indicator extension driverD Scott Phillips1-0/+12
On Ampere Altra, PCIe hotplug is handled through ACPI. A side interface is also present to request system firmware control of the hotplug Attention Indicators. Add an ACPI PCI Hotplug companion driver to support Attention Indicator control.

2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada1-1/+1
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <[email protected]>

2016-06-21PCI/hotplug: PowerPC PowerNV PCI hotplug driverGavin Shan1-0/+13
This adds standalone driver to support PCI hotplug for PowerPC PowerNV platform that runs on top of skiboot firmware. The firmware identifies hotpluggable slots and marked their device tree node with proper "ibm,slot-pluggable" and "ibm,reset-by-firmware". The driver scans device tree nodes to create/register PCI hotplug slot accordingly. The PCI slots are organized in fashion of tree, which means one PCI slot might have parent PCI slot and parent PCI slot possibly contains multiple child PCI slots. At the plugging time, the parent PCI slot is populated before its children. The child PCI slots are removed before their parent PCI slot can be removed from the system. If the skiboot firmware doesn't support slot status retrieval, the PCI slot device node shouldn't have property "ibm,reset-by-firmware". In that case, none of valid PCI slots will be detected from device tree. The skiboot firmware doesn't export the capability to access attention LEDs yet and it's something for TBD.

Convert acpiphp to be builtin only, with no module option. Previously, when HOTPLUG_PCI_ACPI=m, users could disable acpiphp by removing the module or preventing it from loading. That can't be done if acpiphp is builtin statically, so this adds an "acpiphp.disable" kernel parameter. If a user needs to use this parameter, it is a bug, and we want to hear about it.

2012-11-30s390/pci: PCI hotplug support via SCLPJan Glauber1-0/+11
Add SCLP PCI configure/deconfigure and implement a PCI hotplug controller (s390_pci_hpc). The hotplug controller creates a slot for every PCI function in stand-by or configured state. The PCI functions are named after the PCI function ID (fid). By writing to the power attribute in /sys/bus/pci/slots/<fid>/power the PCI function is moved to stand-by or configured state. If moved to the configured state the device is automatically scanned by the s390 PCI layer. Signed-off-by: Jan Glauber <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>
2012-08-24PCI: Remove the fakephp driverBjorn Helgaas1-23/+1
The fakephp driver was scheduled for removal in 2011. Fakephp presented /sys/bus/pci/slots/.../power files for every PCI function. Writing "0" to one of these files logically removed the device from the system. The PCI core now provides the same functionality with /sys/bus/pci/devices/.../remove.

2009-06-18PCI: drivers/pci/slot.c should depend on CONFIG_SYSFSAlex Chiang1-1/+1
There is no way to interact with a physical PCI slot without sysfs, so encode the dependency and prevent this build error: drivers/pci/slot.c: In function 'pci_hp_create_module_link': drivers/pci/slot.c:327: error: 'module_kset' undeclared This patch _should_ make pci-sysfs.o depend on CONFIG_SYSFS too, but we cannot (yet) because the PCI core merrily assumes the existence of sysfs: drivers/built-in.o: In function `pci_bus_add_device': drivers/pci/bus.c:89: undefined reference to `pci_create_sysfs_dev_files' drivers/built-in.o: In function `pci_stop_dev': drivers/pci/remove.c:24: undefined reference to `pci_remove_sysfs_dev_files' So do the minimal bit for now and figure out how to untangle it later.

2009-06-11PCI Hotplug: cpqphp: don't use pci_find_slot()Alex Chiang1-1/+1
Convert uses of pci_find_slot to modern API. In the conversion sites, we end up calling pci_dev_put() right away. This may seem like it misses the entire point of doing something like pci_get_bus_and_slot(), since we drop the reference so soon, but it turns out we don't actually do much with the returned pci_dev. I plan on untangling cpqphp further, but clearly cpqphp never worried too much about a properly refcounted pci_dev anyway. For now, this conversion seems reasonable, as it gets rid of the last in-tree caller of pci_find_slot. Signed-off-by: Alex Chiang <[email protected]> Signed-off-by: Jesse Barnes <[email protected]>

It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing and for section-checking coverage. But a few things go and select CONFIG_HOTPLUG, making it a royal PITA to turn the thing off. It's only turnable offable if CONFIG_EMBEDDED anyway.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
